Problem description: | |
During failover, DB2 leaves non-concurrent Enhanced-Capable(EC) volume groups(VGs) in varied-on mode on the standby node. As a result, this introduces the possibility of unexpected changes to the DB2 files on the affected file systems. This APAR addresses this issue by allowing non-concurrent EC VGs to be varied off during a DB2 failover. This is achieved by removing the following check from the mountV97_stop.ksh script: '$concurrent != "Enhanced-Capable" &&' This check is being made in two places: 1) ################################################################ # Start main... rc=0 if [[ "${rlv}" == "true" && $concurrent != "Enhanced-Capable" && "X$vfs" != "Xmmfs" && -z $isVgManaged ]]; then # RLV logger -i -p notice -t $myname "$vgname is RLV" varyoffvg ${vgname?} ... 2) # Filesystem is unmounted or was not mounted if [[ "${UNAME}" == "AIX" && $concurrent != "Enhanced-Capable" && "X$vfs" != "Xmmfs" && -z $isVgManaged ]]; then varyoffvg ${vgname?} lspvLine=$(lspv -L | grep " $vgname ") vgactive=$(echo $lspvLine | awk '{print $4}') ... | |
